MONOBLOC AIR-COOLED INTERNAL COMBUSTIN ENGINE CYLINDER 3 Sheets-Sheet 3 Filed Nov. 18, 1963 United States Patent O This invention relates to'a monobloc air-cooled piston engine cylinder for 'an internal combustion engine. In particular, this invention is directed to a monobloc cylinder having an integral liner forming the working surface for a piston. This cylinder is usable in all types of reciprocating machinery, but is particularly applicable toan air-cooled internal combustion engine. Cylinders of this type are often composed of alight metal alloy and iitt'ed with a cast iron or steel liner. In view of the high thermal stresses currently permissible in automotive internal combustion engines, especially diesel engines, very high pressures and workingy temperatures occur and produce high stresses and steep temperature gradients which must be accounted for. It is important that the light metal alloy used for the cylinder should be an alloy having good heat dissipation properties and, above all, has a suiliciently high strength to ensure that the cylinderA head-portion of the monobloc can resist the high compression and combustion pressures in the cylinder.
A cylinder composed of a single light metal casting with aliner inserted or'pressed in the cylinder is well adapted to Vmeet these conditions. However, sucha light metal cylinder'has the disadvantage in that combined high tensile and bending stressesoccur at the transition betweenV the cylinder head portion and the cylinder portion of the monobloc which necessitates largecross-sectional areas in this region of the casting. This means that only short cooling iins can be used, especially in the case of multicylinder engines due to the necessary narrow spacing between the cylinders in the central vertical plane through the crank shaft. In other words, the cooling fins must be made shorter between cylinders rather than being preferably circular. This causes unequal heat dissipation and may result in thermal difficulties from heat concentrations which, in turn, causes greater cylinder distortionsthan in the' case where the tins were -truly circular. In addition, such tends to adect the stiffness ofthe Vcylinder inthe lane of the crank shaft.v Y
The object of this invention is to avoid such diculties by reducing the bending stresses in the transitional area between the cylinder head portion and the cylinder portion of the monobloc which, in turn, permits a smaller cylinder diameter and longer cooling fins, or, alternatively,
a closer cylinder spacing.
In general, this invention provides that'the transitional area between the cylinder head portion and the cylinder portion be relieved from tensile and bending stresses by having the liner extended into the cylinder head portion and tightly joined to the head portion. In addition, this liner extension is designed so that the liner receives a large portion of the forces occurring on the cylinder'head portion. This means that the cross-sectional area of the cylinder can be made smaller and the cooling iins made larger, or a closer cylinder spacing can be used. Y Moreover, an additional iirm anchorage of the liner is obtained by casting the liner in the cylinder head portion.
An improved feature of this invention isobtained by forming radially Vdirected holes in the lliner extension,
which holes are lled with the cylinder material when the cylinder is cast around the liner. This forms an absolntely rm joint between the liner and the cylinder head 'Y anothermodication of the invention; and
a ing another modiiication of the invention;
FIGURE 4 is a view similar .to FIGURE Z-'andV show-` rice e Patented Janf19, 1965 extension. Such-shapes givea larger surface contact area and consequently lower stresses per unit of surface area, as well as a positive connective joint.
Intanother moditication of the invention, at least two studs or bolts are formed either integral with the liner or screwed to the top end ofthe liner and preferably arranged diametrically across the liner. These bolts or studs pass through the cylinder head portion. A bridge means preferably formed vof steel rests on the center of the cylinder head por-tion between the bolts and held by a nut threaded on the end of each bolt. This reduces deflectionof the cylinder head'portionto a minimum so that they are practically eliminated and the bending stresses in the transition zone between the cylinder`:head portion and the cylinder portion substantially disappear.V
e In a further modiiication of this invention, the bridge v means between theV bolts is composed ofja housing for the valve rocker armsv and their ttings. As'the housing is hollow, it can be designed with a complete stiiness with no bending and takes up fiection.
The means by which the objectsof the invention are obtained are described more fullyVV with reference tothe accompanying drawings in which;

In FIGURE l, the liner 1 has cast around it a iinned cylinder 2 so that it is integral withV the cylinder head.
The casting is preferably done by an aluminium vbonding process. The intake port 4 and the exhaust port `5 are formed in the cylinder head portion 3. `Liner 1 has an extension 1a extending into the head portion so that theV casting is on both sides of the extension'and produces `a securely placed or shrunk joint between the liner and formly around the circumference. The cast cylinder material ows through these holes to form an additional con-tV nection between the liner and the head portion.V Y
In the modification of VFIGURE 3, the extension 1 is in the shapeY of a dove-tail so that a Vdove-tail joint 7 is formed between theliner 1 and the cylinder head por-` tion 3.

' Threaded endsZ of the bolts receive nuts 13 so that the bridge 11 is tightened against the cylinder head. Comequently, the gasV pressures acting on head portion 3 are transferred through bridge 11 and bolts'10 torliner 1 with theresult thatthe head portion 3 is Vstiienedand bending stresses in the transition zone between head portion 3 and cylinder portion 2 disappear almost completely.
